This behavior is controlled by the `winreadlinkvolume` setting.
For Go 1.23, it defaults to `winreadlinkvolume=1`.
Previous versions default to `winreadlinkvolume=0`.

Go 1.23 enabled the experimental post-quantum key exchange mechanism
X25519Kyber768Draft00 by default. The default can be reverted using the
[`tlskyber` setting](/pkg/crypto/tls/#Config.CurvePreferences).

Go 1.23 changed the behavior of

			"This should be a different port than typically used by etcd to avoid clients accidentally connecting during upgrade/downgrade operations. "+
